Exception in socket programming

[gReaen]

Hello everyone I'm doing a single client server application. After receiving a file from the client, server gets closed with the following exception. Debug assertion failed! Program: path of file File: winhand.cpp Line: 229 But the file is getting transferred correctly. And i need to send more than one file without connection being closed. Plz help...

First use GetLastError() to check the error number and find out what the exact problem is. It may be in either application which closes the socket after receiving/sending. Or it can be possible that the socket was declared locally inside a function, that's why on exit the socket is released. Try GetLastError first to check the error code. :) Also you should put some checking on the returns of the socket functions to check if the function was successful, otherwise it wouldn't have been generating assert errors like that, just failure to do the functions correctly.
